不同生育期施锌效果有较大差异,苗期每亩施1—2公斤硫酸锌能使浙贝叶面积增大,株高、二秆数增加,枯萎延迟、干物质、生物碱含量也略有提高,明显增加产量(达0.01显著水平)效益可观。
Applying zinc fertilizer had a promoting effects on the growth of Fritillarly.The effects of
applying ZnSO_4 were evidently different at various growing-stages.The results of applying 0.5—2
kg/mu Zinc sulphate were suitable for raising leaf area,stem height,and yield of Fritillary ect.
Spraying ZnSO_4 increased the amount of Fritillary alkaloids at the late stage.
